Specification of Letters Patent.

Patented May 21, 1907.

Application filed September 15,1905 Serial No. 278,603.

To all whom it may concern:

Be it known that I, CARL RAYER, merchant, a subject of the German Emperor, and a resident of Esslingen, Germany, have invented certain new and useful Improvements in and Relating to Gas-Boilers, of which the following is a specification.

The present invention relates to gas boilers, which are so constructed, that a large quantity of water is flavorless and scentless heated during the boiling. The burners of said gas boilers are provided with an arrangement for a quick vertical adjustment of the regulation of the gases and the air.

The object of my invention is to improve gas boilers so that the water heated in the same shall be clean scentless and Without of reference refer to corresponding parts throughout the different views of the drawlng.

Figure 1 shows a plan view of such a gas boiler partly in section, Fig. 2 shows a cross section through the gas boiler on lines II Fig. 1, Fig. 8 shows a cross section through the gas boiler on lines IIII Fig. 1, Fig. 4 shows a side view of one of the burners.

' The gas boiler consists of a water receptacle b which rests on the supports a. This rece tacle may be preferably manufactured of s eet-copper or similar thin flatted material. The receptacle 7) is provided at any suitable place with a water reservoir for instance a water tower, c which can be closed or opened by means of a cover (1 for the purpose of taking water out of the receptacle. A discharge-cock e is provided on the watertower a. The openings f serve on one hand to receive the gas burners i on the other hand to offer a sufficient surface of the receptacle to the burning gases for the purpose of heating the water contained in the said receptacle. Three supports 9 are arranged around the adjustable burners h inside of the said openings f, and they serve to carry the pots with the food. The burners h consist of the gas collecting chamberi and the adjustable head piece is. The head pieces 7c is mounted on a shaft Zwhich passes through the gas collecting chamber 'i and is provided on its lower end with a pin m. The gas collecting chamber is provided on its bottom with a short tube 0 which is provided with a slit n. The head piece 7c and its shaft Z with the pin m is so inserted into the gas collecting chamberi and the tube 0 that the pin m turns screwlike in the slit n as soon as the head piece is turned. According to the direction in which the head piece 7c is turned is the air regulated which is to be added to the burning gases by means of enlarging or diminishing the space between the head piece is and the gas chamber i. A plate 72 with openings q is placed on the receptacle b. Correspondmg to the openings f the size of the openings 9 may be reduced according to the size of the tops by means of common fitting rings 1.

What I claim as new and desire to secure by a United States Letters Patent is: 1. In gas boilers the combination of a water chamber supported on feet, cylindrical passages in said water chamber from top to bottom and closed at the bottom, said cylindrical passages being encompassed laterally by the water chamber, gas burners inserted through the bottom, supports for cooking vessels arranged round said burner, and a hot .water reservoir in communication with and higher than the water chamber, all substantially as and for the purpose set forth.

2. In gas boilers the combination of a Water chamber supported on feet, cylindrical passages closed at the bottom and encompassed laterally by the water chamber, a hot water reservoir in communication with the water heating chamber, gas burners inserted through the bottom, a gas mixing chamber of round form, a central support, a head piece adapted to fit over said gas mixing chamber, and a lateral projection on the lower part of the support adapted to work in a spiral, substantially as and for the purpose set forth.

8. In gas boilers as herein described gas burners comprising the combination of a delivery tube, a gas mixing chamber of round form, a head piece to said chamber, a central support for said head-piece passing through the mixing chamber, a lateral projection near the bottom of the central support, a 1905, in the presence of two subscribing witspiral groove in the tubular lower part of the nesses. mixing chamber, said lateral rojection being 7 CARL BAYER adapted to move in said spira groove all sub- 5 stantially as and for the purpose described.

In testimony whereof I ave hereunto GOTTLIEB RIMIG, signed my name this 29th day of August WM. HAHN.
